Abstract

A fuel cell with components having durable ultraphobic surfaces at selected locations where condensation of water may occur. The ultraphobic surface generally includes a substrate portion with a multiplicity of projecting microscale or nanoscale asperities disposed so that the surface has a predetermined contact line density equal to or greater than a critical contact line density.
